Flex Sensor 4.5" Introduction
A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove. I love the Nintendo Power Glove. It's so bad!
The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on insid..
Gravity: Analog AC Current Sensor Introduction
When you want to measure AC current it is impractical and hazardous to cut in to your live wiring. The analog AC current sensor developed by DFRobot is a good solution to this problem. Using induction you can measure AC current without intrusive methods. Place your AC wire inside the unit, connect the unit to the sensor board using the 3.5mm jack connector and connect the sensor bo..
Gravity: Analog CO2 Gas Sensor For Arduino Introduction
"Greenhouse Effect" is melting the Earth ice core every minute and creating dangerous icebergs. By knowing the exact concentration of CO2(Carbon Dioxide), we can do something to reduce the CO2 and to protect our Earth. Here is the CO2 sensor designed by DFRobot lovely engineer. This is the first CO2 sensor in Arduino market. The output voltage of the module falls as th..
Gravity: Analog Heart Rate Monitor Sensor (ECG) For Arduino Introduction
The DFRobot Heart Rate Monitor Sensor is used to measure the electrical activity of the heart. This electrical activity can be charted as an ECG and output as an analog reading. An ECG signal can be extremely noisy so we have included an AD8232 chip which will generate a clear signal from the PR and QT Intervals. Using the Arduino IDE "Serial Plotter" feature, you are also abl..
Gravity: Analog High Temperature Sensor Introduction What sensor should you use when you need to measure temperature? Most people will think of a DS18B20 temperature sensor first, but this sensor is only capable of measuring temperatures up to 125C. In order to measure temperatures greater than 100C you will need something with a greater temperature range and resistance. This is the sensor you need! We have used a PT100 resistance type ..
